A pig house that can collect pig manure, pig urine and flushing water separately

technical field

The invention relates to a pig house capable of separately collecting pig manure, pig urine and flushing water, which is a new approach for reducing pollutants in pig farms and belongs to the field of agricultural environmental protection.

Background technique

In recent years, large-scale centralized breeding of livestock and poultry has developed rapidly. At the same time, it has also brought about excessive concentration of livestock and poultry manure and a large increase in flushing sewage. Since most farms have failed to effectively treat and utilize livestock and poultry manure, The problem of livestock and poultry manure pollution has become increasingly prominent. According to the announcement of the first national survey of pollution sources, the national livestock and poultry breeding industry produced 243 million tons of feces, 163 million tons of urine, and the discharge of major water pollutants: 12.6826 million tons of chemical oxygen demand, 1.0248 million tons of total nitrogen, The total phosphorus was 160,400 tons, accounting for 41.9%, 21.67% and 37.9% of the national water pollutant discharge respectively. Livestock and poultry pollution has become an important source of pollution in the current agricultural, rural and water environment. For this reason, the state will soon introduce relevant policies to include the reduction of farm pollutants as one of the important contents of national pollutant emission reduction.

All countries have invested a lot of manpower, material and financial resources in the treatment of excrement pollution from livestock and poultry breeding industry. However, due to the large amount of pollutant discharge and high concentration of pollutants in farms, and the relatively low efficiency of breeding enterprises, it is difficult to adopt and promote the application of factory Therefore, how to effectively reduce the production and discharge of farms has become the most important technology for aquaculture excrement pollution control.

The invention patent with the application number CN201210223585.4 provides a kind of manure leakage board for farms, including the manure leakage board body, and at least two slits are arranged on the manure leakage board body, so that pig manure and urine can directly leak into the bottom layer.

The utility model patent with the application number CN201120342935.X provides an improved pig farm, including pens, the bottom of the pens is covered with a bedding layer, the bottom of the bedding layer is provided with an anti-leakage layer, and the bedding layer There is a slatted floor in the upper part of the pen, and its advantages are: the slatted floor is used to separate the pigs from the bedding layer for breeding, so that the growth of the pigs is more comfortable, the environment is better, and it is easy to clean.

The utility model patent whose application number is CN200420047247.0 provides a kind of high-rise bed raised from the ground specially for pig farms, including support beams, feet and cast iron slats. The upper plane of the beam is provided with a sunken plate connection groove, and the two ends of the support beam are provided with a T-shaped inclined plane expansion head with a wide top and a narrow bottom. The two ends of the beam are lapped in the T-shaped groove of the support foot through the T-shaped inclined-plane enlarged head to form a cast iron slatted plate support body.

The above three patents all propose to install a dung leaking board in the piggery to leak feces and urine into the bottom layer, save the daily flushing of the piggery, and reduce the amount of sewage generated.

The utility model patent with the application number CN201020681118.2 proposes a water-saving cleaning device for washing and disinfecting animal farm pens, including a spray gun, and the output end of the spray gun is covered with a nozzle. The water-saving cleaning device also includes A pressurized air storage device connected with the spray gun through an air outlet hose and a water storage device connected with the spray gun through a water outlet hose. In the utility model, the water and air are sprayed from the nozzle at the same time, which not only increases the speed of the water flow, but also saves the amount of water. The patent provides a method and a device for reducing flushing water.

In addition, the fermented bed breeding technology currently being promoted and applied in many provinces and cities in my country is also an effective technical way to reduce the amount and emission of pollutants in farms. The basic method is to fill the specially designed pigsty with organic litter, such as wood chips, and then put the piglets into the pigsty. The pigs live on the organic litter from childhood to slaughter. The pig excrement is absorbed by the organic litter and rapidly degraded and digested by the microorganisms in it. In daily management, it is no longer necessary to manually clean the pig excrement to achieve the goal of zero discharge.

The above patents all provide different technical means for reducing the discharge of excrement in farms. Among them, the method of leaking manure board can reduce the flushing water, but due to the need to increase the building height of the pig house and install the leaky manure board, it will increase the pig house. Construction costs, and the water content of the collected manure brings difficulties to the subsequent treatment; the use of fermentation bed pig raising technology can achieve the goal of emission reduction or even zero emission, but the high cost of litter also hinders the fermentation bed technology further promotion and application. In addition, all patented technologies do not mention methods and means for separating pig manure, urine and flushing water.
